15.6.3.5 Application of top coat
CAUTION
For repairing it is necessary to choose the identical type (single coat, double coat) of the
repair color as on the original surface.
Application of the top coat will be carried out by spraying as for the total spray coat (see
15.6.2.3) with the exception of used thinners and hardeners. Due to the need of smooth
transition to the basic surface it is necessary to use so called „spraying into the surface" using
longer time of drying initiations for a good result of work. The recommended material is shown
in Tab. 15-8.
